Providone-iodine is used as a topical antimicrobial in burn patients. Although absorption of iodine has been thought to be negligible, several patients have recently been noted with substantial elevations of serum free iodide. Unexplained abnormalities occurred in several of these patients, renal failure, metabolic acidosis, and elevation of serum glutamic oxaloacetic transaminase. It is conceivable that the large iodide loads noted were at least in part responsible for these abnormalities.
A case of unilateral ureteral obstruction owing to extensive pelvic endometriosis is presented. There was complete resolution of ureteral obstruction following treatment with synthetic progestin. Sequential assessment of renal function was provided by renal imaging and renograms. It would appear that selected patients with obstructive uropathy may respond favorably to medical management, which would allow for preservation of reproductive capabilities and restoration of renal excretory function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
